Evan Cheng 6476a3b4ba Darwin X86 external weak linkage support. 
llvm-svn: 32065
 2006-12-01 07:15:24 +00:00
Anton Korobeynikov 12c94949e0 Introducing external weak linkage. Darwin codegen should be added later.

Evan Cheng a41c2d6432 Nuke dead code. 
llvm-svn: 31327
 2006-10-31 21:53:31 +00:00
Anton Korobeynikov aa4c0f9374 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

llvm-svn: 31311
 2006-10-31 08:31:24 +00:00
Anton Korobeynikov 49993529eb Unbreaking static ctors patch. 
Defaulting second arguments of SwitchTo*Section, this should make things
somehow clearer.

llvm-svn: 31306

Reid Spencer 2545fe6d93 Make this compile again. 
llvm-svn: 31304

Evan Cheng de5ecd6bc1 Apply Aton's LLVM patch for PR973: Linux ctors / dtors support. 
llvm-svn: 31303
 2006-10-31 01:26:55 +00:00
Reid Spencer b51b5c0b1f Add debug support for X86/ELF targets (Linux). This allows llvm-gcc4 
generated object modules to be debugged with gdb. Hopefully this helps
pre-release debugging.

llvm-svn: 31299

 2006-10-24 20:32:14 +00:00
Anton Korobeynikov 41a83d7871 Do section switching right way for Mingw\Cygwin and Linux. 
This will allow (after llvm-gcc linkage fix) more dummy tests using
libstdc++ to pass on mingw :)

llvm-svn: 31120
 2006-10-22 21:37:13 +00:00
Anton Korobeynikov 24b7ac303c Fixed mingw\cygwin linkonce linkage once again. 
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.

llvm-svn: 31033
 2006-10-18 09:12:29 +00:00

Anton Korobeynikov 6f7072c66a Added some eye-candy for Subtarget type checking 
Added X86 StdCall & FastCall calling conventions. Codegen will follow.

llvm-svn: 30446
 2006-09-17 20:25:45 +00:00
Anton Korobeynikov d61d39ec53 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference. 
This fixes PR 759.

llvm-svn: 28056
 2006-05-02 17:34:51 +00:00
Nate Begeman b9d4f8324d Extend printBasicBlockLabel a bit so that it can be used to print all 
basic block labels, consolidating the code to do so in one place for each
target.

llvm-svn: 28050
 2006-05-02 05:37:32 +00:00
Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Chris Lattner 618981fd03 Naturally align doubles in the constant pool, set PrivateGlobalPrefix on 
darwin, use it when printing the constant pool indices so the labels are
